Looks jps will work, only if the jdk is installed. As in my environment only jre is installed.
so tried installing jdk like below
yum list java*devel*
Loaded plugins: langpacks, ulninfo
Available Packages
java-1.6.0-openjdk-devel.x86_64 1:1.6.0.41-1.13.13.1.el7_3 ol7_latest
java-1.7.0-openjdk-devel.x86_64 1:1.7.0.261-2.6.22.2.0.1.el7_8 ol7_latest
java-1.8.0-openjdk-devel.i686 1:1.8.0.252.b09-2.el7_8 ol7_latest
java-1.8.0-openjdk-devel.x86_64 1:1.8.0.252.b09-2.el7_8 ol7_latest
[root@cloudera opt]# yum install java-1.8.0-openjdk-devel.x86_64
Now i can issue jps and it shows all the hadoop services running.
Thanks
